ANTISKIDDING DEVICE.

Specification of Letters Patent.

Patented Jan. 24, 1911.

To all whom it may concern:

Be itknown that I, WILLIAM P. SOHOLL, a citizen of the United States,residing at South Bethlehem, in the county of Northampton and State ofPennsylvania, have inhas its periphery and useful Antiskidding Dethefollowing is a specificavented a new vice, of which tion.

It is the object of the present invention to provide a novel andefficient anti-skidding device for vehicles and the device embodying thepresent invention is designed particularly for use on automobiles toprevent side skidding which is liable to occur on wet, slippery or verydusty roads.

The invention aims, among other things, to provide a device of thecharacter which may be readily actuated without necessit of the operatorof the machine removing his hands from the steering wheel or lever.

Further the invention aims to provide a device of the character whichwill not be liable to become displaced.

In the accompanying drawings :F igure 1 is a view in side elevation ofthe device. Fig. 2 is a front elevation thereof. Fig. 3 is a horizontalsectional view on the line 33 of Fig. 1.

In the drawings, there is shown an automobile axle, 5 (preferably therear axle) and a portion of the floor of the body of the automobile. Acasing 7 is provided at its upper end with a sectional collar 8 which isclamped about the axle 5 near one of the wheels and the casing is inthis manner sup ported in depending position from the said axle. Thecasing as is clearly shown in Fig. 3 of the drawings, is rectangular ina cross section, one side 9 thereof being removable and being bolted inplace. A wheel carrying head 10 is formed with an upstanding stem 11which fits exactly within the casing 7 and is slidable therein. Toprevent complete removal of the stem from the casing, the wall or side 9of the latter is formed with a slot 12 and a stud bolt 13 is threadedinto the stem and engages through and works in the said slot 12. It willbe observed from an inspection of the Fig. 1 of the drawings that thestem projects from the head 10 at a point midway between the endsthereof and that the said head is located in a plane parallel to theplane of the wheel at the adjacent end of the axle (see Fig. 2). Furtherthe head 10 at each end is bifurcated as at 14 and a wheel 15 isjournaled in each bifurcation. Each of the wheels 15 16 so beveled thatthe wheel as a whole has the form of a truncated cone the base of whichis presented to the adjacent vehicle wheel. At this point it will bestated that the head 10 is lowered so as to bring the wheel 15 intocontact with the road surface, the sharp edges of the periphcries of thewheels will dig into the road surface and side skidding will beprevented.

Normally the head is held elevated through the medium of a spring 17which is mounted upon a rod 18 at the upper end thereof. This rod 18engages slidably through a bracket 19 which is clamped to and dependsfrom the axle 5. The lower end of the rod 18 is secured to the head 10at a point midway the ends of the same and the spring 17 bears at itslower end against the bracket 19 and at its upper end against a head orstop at the upper end of the said rod 18.

The side or wall 9 of the casing of the device is formed with anextension 20 upon which is mounted to rock, an angle lever 21 one arm ofwhich normally extends approximately horizontal and is slotted as at 22;the other arm extends approximately vertical. The stud bolt 13 engagesthrough the slot of the first mentioned arm so that rocking of the anglelever will result in an up or down movement of the head 10 and its stem11 upon which latter the stud bolt 13 is carried as heretofore stated.In order that the angle lever may be manually rocked, a rod 23 ispivoted at its rear end to the upper end of the vertical arm of theangle lever and its forward end to the lower end of a foot lever 24which is mounted in the floor 6 of the automobile as shown in Fig. l ofthe drawings.

It is preferable that one of the above described devices be arranged ateach side of the vehicle and that the devices be independently operableso that skidding either to the right or left may be prevented. It willbe understood of course that the foot lever 24 is to be forwardly rockedto lower the wheel carrying head against the tension of the spring 17and that the said spring will act to automatically return the head toelevated position when the "foot lever is released.

That is claimed is In a device of the class described a casing, one Wallof said casing being removable and being slotted, a head having a stemslidably fitted in said casing, Wheels carried by the stem, a studcarried by the stem and engaging through the slot in the said remov ableWall of the easing an angle lever mounted to rock on said Wall andconnected to said stud, a foot lever, and connection be-- tween saidangle lever and foot lever.

In testimony that I claim the foregoing 15 as my own, I have heretoaffixed my signature in the presence of two Witnesses.

WILLIAM P. SCHOLL.
